  When using "While" loops I always add this condition to prevent infinite loops:

  loopindex<100000

  So even if you create an infinite loop by accident, at least it won't freeze.

  If the task is not to spawn too close to the player, you can in first condition filter all spawn points by distance, then pick a random one among them:

  System pick Spawn by evaluate distance(Spawn.x, Spawn.y, player.x, player.y)>200

  System pick random Spawn

  Everything is possible of course. You can pick all objects in the inventory, loop through inventory slots moving each object to a new slot.

  Can be global, or it can be an instance variable on the button for example.

  For example:

  Variable odds=50
  
  On button clicked 
  
  .. If random(100)<Odds : // success
  .. Else : // fail
  
  .. Subtract 10 from odds
  

  Every click will reduce the odds by 10%. Starts at 50%, and after 5 clicks will be zero.

  You can move multi tile map squares at once but I want each one to count as a "turn."

  Do you want to allow moving multiple tiles at once? Then calculate the distance, divide by tile size and you get the number of turns. Add it to the variable.

  I have never heard about a Scratch game, and google doesn't know about it either. Did you mean Scrabble by any chance?

  "Trigger once" should never be used with objects that have multiple instances.

  jawad2heaven Simply create a sub-event in "On left button clicked", and move the second event there. You won't even need the "clicked" variable.

  And you can use "On object clicked" instead of checking if cursor is over the sprite.

  I hope your objects A, B and C are actually 3 instances (copies) of the same sprite?

  Anyway, you need to post your code or project file.

  Not sure how well it would work with the player in motion though.

  If a separate 'base' sprite with Platform behavior is used, you can attach the rotator sprite to it, attach player sprite to the rotator. At the end of the jump remove the rotator sprite, re-attach the player back to the base sprite.

  Add an instance variable IsOccupied to the placeholder sprite.

  When object A/B/C clicked, pick the first placeholder sprite with IsOccupied=0. Move the object to it and set its IsOccupied to 1.

  Here is another solution - click any point on the sprite:

  No, r should be a global or a local variable, not instance variable.
